Description

薄膜过滤管系统Membrane Filter Tube System

发明领域field of invention

本发明涉及一种薄膜过滤管系统。更确切地，本发明涉及一种用于中空纤维薄膜过滤器的薄膜过滤管系统，该系统包括细长的中空纤维薄膜束，其中需要过滤的物料是通过运送到纤维束外部而进行过滤的，而滤出液是从纤维内腔的一端或若干端进行排出的。上述系统同样最好包括用于对纤维供料表面进行定期性清洗的清洗装置。The invention relates to a membrane filter tube system. More precisely, the present invention relates to a membrane filter tube system for a hollow fiber membrane filter, the system comprising bundles of elongated hollow fiber membranes, wherein the material to be filtered is filtered by being conveyed outside the bundle, The filtrate is discharged from one or several ends of the fiber lumen. The above system also preferably includes cleaning means for periodically cleaning the fiber supply surface.

本发明一直主要应用在对大气压力开放的薄膜过滤系统中，以下将对此进行描述。然而，应当理解到本发明并不限于上述特定的使用领域。The invention has been primarily used in membrane filtration systems open to atmospheric pressure, as will be described below. It should be understood, however, that the present invention is not limited to the specific fields of use described above.

现有技术的描述Description of prior art

现有技术中通常的过滤管是应用在上述过滤系统中。这些过滤系统通常包括细长管状滤芯，其包围着一束中空纤维薄膜。管或集管的布置用于连接上述芯，通常在一端或两端进行连接，这些管用来使污染的物料、滤出液以及清洗液的各个流动通过该系统发生分离和转向。在此，横流系统通常具有两个物料管(进口和再循环出口)以及一个或两个过滤管。在现有技术的横流过滤系统中，需要被过滤的物料流与薄膜表面相切或穿过薄膜表面而流动。这就对薄膜表面产生了一个清扫作用，使其更清洁。相反，设置为闭端操作的系统在过滤模式中仅能利用一个物料入口管和一个过滤出口管。另外，这些现有技术中管或集管的布置常常设置成为方便构造成模块化的两维或三维芯阵列。Common filter tubes in the prior art are used in the above filter system. These filtration systems typically consist of an elongated tubular filter element surrounding a bundle of hollow fiber membranes. An arrangement of tubes or headers is used to connect the cores, usually at one or both ends, and these tubes are used to separate and divert the individual flows of contaminated material, filtrate and cleaning fluid through the system. Here, cross-flow systems generally have two material pipes (inlet and recirculation outlet) and one or two filter pipes. In prior art cross-flow filtration systems, the stream of material to be filtered flows tangentially to or across the membrane surface. This creates a sweeping action on the surface of the film, making it cleaner. In contrast, a system set up for closed-end operation can only utilize one material inlet tube and one filter outlet tube in filter mode. Additionally, these prior art arrangements of tubes or headers are often arranged in such a way that they are conveniently constructed as modular two- or three-dimensional arrays of cores.

更典型地，现有技术中的过滤系统如上所述，相对大气是密闭的。在该系统中，需要过滤的流体(以下称之为物料)是在正压力下被输送到过滤器的。为了使这种类型的系统有效操作，上述细长的管状过滤筒被装入气密外壳中。这种外壳随后再与既分离物料和滤出液又支承该气密外壳的过滤管管系统相连。这种过滤管系统也可以用于将清洗液引入过滤系统。More typically, prior art filtration systems, as described above, are closed to the atmosphere. In this system, the fluid to be filtered (hereinafter referred to as material) is conveyed to the filter under positive pressure. In order for this type of system to operate efficiently, the aforementioned elongated tubular filter cartridge is encased in an airtight enclosure. This housing is then connected to a filter tube system which both separates the material and filtrate and supports the airtight housing. This filter tube system can also be used to introduce cleaning fluid into the filter system.

现有技术中的过滤系统，如上所述，也可以对大气环境开放。在该系统中很典型的是，物料是在负压力下穿过薄膜进行提取的。这是通过在薄膜的滤出液侧施加一个负压力或吸力而实现的。这种系统相比与大气相密闭的系统而言易于应用更少的基础设施和基本工作，这是因为它们不再需要要求具有相对较高压力的元件。例如，在对大气开放的系统中，无需将过滤筒装入单个气密外壳中。在这些系统中很典型的是，过滤筒仅仅是基本浸入一个装有物料的开口箱中。在这个系统中，希望设置一个合适的管，用来支承过滤筒并使滤出液在分离出物料和滤出液的同时从过滤器中抽取出。相似地，与密闭系统一样，这种过滤管也可以用于支承一个清洗液系统的目的。Filtration systems in the prior art, as described above, may also be open to the atmosphere. Typically in this system, material is extracted through a membrane under negative pressure. This is accomplished by applying a negative pressure or suction on the filtrate side of the membrane. Such systems tend to employ less infrastructure and capital work than systems closed to the atmosphere, since they no longer require components requiring relatively high pressures. For example, in a system that is open to the atmosphere, it is not necessary to house filter cartridges into a single airtight housing. Typically in these systems, the filter cartridge is only substantially submerged in an open box containing the material. In this system, it is desirable to provide a suitable tube for supporting the filter cartridge and allowing filtrate to be drawn from the filter while the material and filtrate are being separated. Similarly, as with closed systems, such filter tubes may also serve the purpose of supporting a cleaning fluid system.

现有技术的过滤系统及其相关的上述过滤筒通常具有复杂的管道和部件布置，组装起来很困难并且费时。另外，现有技术的过滤系统中实际的过滤管系统元件自身也常常是一个复杂的部件组合。Prior art filtration systems and their associated aforementioned filter cartridges typically have complex piping and component arrangements that are difficult and time consuming to assemble. Additionally, the actual filter tube system components in prior art filtration systems are often a complex assembly of components themselves.

上述现有技术的过滤系统也需要常规检测来评定系统的完整性。不完整可能是由于单个过滤薄膜中空纤维、O型圈或其它系统元件的故障。完整性检测通常需要拆卸任一单个系统元件或者过滤筒。在现有技术的传统过滤管中通常很难进行上述的拆卸操作。另外，如上所述，现有技术的过滤管可能包括许多复杂的部件。它随之要进行的对这些部件的完整性检测同样很费时。The prior art filtration systems described above also require routine testing to assess the integrity of the system. Incompleteness may be due to failure of individual filter membrane hollow fibers, O-rings, or other system components. Integrity testing typically requires disassembly of any individual system component or filter cartridge. The above-mentioned disassembly operation is generally difficult to perform in conventional filter tubes of the prior art. Additionally, as noted above, prior art filter tubes may include many complex components. The subsequent integrity checks of these components are likewise time-consuming.

本发明的目的是提供一种在此所述的过滤管系统，该系统至少能克服或改善现有技术中存在的一些缺陷，或者至少能提供一种有用的替代物。It is an object of the present invention to provide a filter tube system as described herein which overcomes or ameliorates at least some of the disadvantages of the prior art, or at least provides a useful alternative.

最佳实施例的描述Description of the preferred embodiment

现在描述视图，薄膜过滤管系统包括一个薄膜过滤管1，用于连接一种包括细长中空纤维薄膜束的过滤子模块2。图1和图2很好地示出，管的最佳实施例包括一个与四个子模块连接轴环4相连的外壳3。Referring now to the views, the membrane filter tube system comprises a membrane filter tube 1 for connection to a filter submodule 2 comprising a bundle of elongated hollow fiber membranes. As best shown in FIGS. 1 and 2 , the preferred embodiment of the tube comprises a housing 3 connected to four submodule connecting collars 4 .

如图3所示，该轴环4适于接纳和定位上述子模块2，上述子模块2设有一个具有锁定凸缘6的连接套管5。在该实施例中，子模块2能在一端被一个夹持装置7固定在相应的轴环4上，上述夹持装置7同时使上述子模块2和锁定凸缘6接合在一起，以便防止子模块2沿轴向从轴环4中脱出。锁定凸缘6进一步与轴环4的唇部8形成支承接合。接合和释放夹持装置7基本上能使子模块2与管1容易地进行相应的组合和拆卸。管1另外还包括一个位于上述外壳3和轴环4之间的用于流体流通的滤出液通道9和一个用于与清洗液管道11实现清洗液流通的清洗液通道10。As shown in FIG. 3 , this collar 4 is adapted to receive and position the above-mentioned sub-module 2 provided with a connecting sleeve 5 with a locking flange 6 . In this embodiment, the sub-module 2 can be fixed at one end on the corresponding collar 4 by a clamping device 7 which simultaneously engages the sub-module 2 and the locking flange 6 together so as to prevent the sub-module from The module 2 emerges axially from the collar 4 . The locking flange 6 is further in bearing engagement with the lip 8 of the collar 4 . Engagement and release of the clamping means 7 substantially enables the corresponding assembly and disassembly of the submodule 2 and the tube 1 with ease. The pipe 1 further includes a filtrate channel 9 for fluid communication and a cleaning fluid channel 10 for communicating with the cleaning fluid pipeline 11 located between the above-mentioned housing 3 and the collar 4 .

图4a、4b和5示出夹持装置7的最佳实施例。该夹持装置7具有一个基本为圆柱形的侧壁12，该侧壁12具有顶部凸缘13和底部凸缘14，每个凸缘都从侧壁12沿径向向内突出。该夹持装置7沿着一条平行与子模块2的直线被分割，以便允许夹持装置在沿轴向滑进或滑出与轴环4的锁定接合时能径向扩展。径向扩展是通过手动分开一对分别设在夹持装置凸缘13上并在裂口两侧上的突出物40而实现的。另外，夹持装置7弹性偏置以便能使夹持装置在其以弹簧锁的方式与子模块2和轴环4以弹簧锁方式接合时进行径向收缩。当使用夹持装置以便使子模块和锁定凸缘接合时，底部凸缘14锁定在子模块凸缘6上方，顶部凸缘13以支承方式与唇部8接合。另外，轴环4具有一个用于与顶部凸缘13进行锁定接合的梯状支座15。Figures 4a, 4b and 5 show a preferred embodiment of the holding device 7. The holding device 7 has a substantially cylindrical side wall 12 with a top flange 13 and a bottom flange 14 each projecting radially inwards from the side wall 12 . The clamping means 7 are divided along a line parallel to the sub-module 2 so as to allow radial expansion of the clamping means when sliding axially into and out of locking engagement with the collar 4 . Radial expansion is achieved by manually separating a pair of protrusions 40 provided on the flange 13 of the holding device on either side of the split. In addition, the clamping means 7 are resiliently biased so as to enable radial contraction of the clamping means when they are snap-lockingly engaged with the sub-module 2 and the collar 4 . When using the clamping means to engage the submodule and locking flanges, the bottom flange 14 is locked over the submodule flange 6 and the top flange 13 engages the lip 8 in a bearing manner. In addition, the collar 4 has a stepped seat 15 for locking engagement with the top flange 13 .

图4c示出夹持装置7的一个替代实施例。该实施例具有附加的突出物41，有助于以手动方式将夹持装置7从子模块2和轴环4上拆下。附加的突出物41沿径向从夹持装置7的侧壁12并在侧壁12裂口的两侧上延伸。FIG. 4 c shows an alternative embodiment of the clamping device 7 . This embodiment has an additional protrusion 41 that facilitates manual removal of the clamping device 7 from the submodule 2 and the collar 4 . Additional projections 41 extend radially from the side wall 12 of the holding device 7 and on both sides of the opening in the side wall 12 .

图7a-c以及图8a-c示出子模块连接套管5的实施例。这些视图示出凸缘6的细节和连接套管5的O形圈支座通道17的特征。凸缘6的一侧18用于与轴环4支承接合，第二侧19用于与夹持装置7锁定接合。另外，图7a-c所示的子模块连接套管5的实施例具有一个用作O形圈支座的管道17，同时图8a-c所示的子模块连接套管5的实施例具有两个用作O形圈支座的管道17。Figures 7a-c and Figures 8a-c show an embodiment of a submodule connection sleeve 5. These views show details of the flange 6 and the features of the O-ring seat channel 17 connecting the sleeve 5 . One side 18 of the flange 6 is intended for bearing engagement with the collar 4 and a second side 19 is intended for locking engagement with the clamping means 7 . Additionally, the embodiment of the submodule connection bushing 5 shown in Figures 7a-c has one conduit 17 serving as an O-ring seat, while the embodiment of the submodule connection bushing 5 shown in Figures 8a-c has two A pipe 17 that acts as an O-ring seat.

管1还可包括一个可拆卸的罩帽，用于与外壳进行气密性的密封接合。图9a和9b示出该罩帽的最佳实施例，其中该罩帽包括一个圆盘21，该圆盘上沿轴向延伸的螺纹轴22沿中心安装在一侧。该圆盘21同样在另一侧具有突出物23，以方便手动旋转罩帽20。该罩帽将在以下进行详细描述。Tube 1 may also include a removable cap for hermetically sealed engagement with the housing. Figures 9a and 9b show a preferred embodiment of the cap, wherein the cap comprises a disc 21 on which an axially extending threaded shaft 22 is centrally mounted on one side. This disc 21 also has a protrusion 23 on the other side to facilitate manual rotation of the cap 20 . The cap will be described in detail below.

一个径向间隔的凸缘24在罩帽与上述轴22相同的一侧上从罩帽20沿轴向向外延伸。该凸缘允许罩帽20与外壳1形成气密性的密封接合。图10示出罩帽20在使用时的最佳实施例。A radially spaced flange 24 extends axially outwardly from the cap 20 on the same side of the cap as the shaft 22 described above. This flange allows the cap 20 to form an airtight sealing engagement with the housing 1 . Figure 10 shows the preferred embodiment of the cap 20 in use.

在如图11所示本发明的另一实施例中，一个薄膜过滤装置25包括一个顶部元件26和一个基部元件27，其中每个过滤装置都是上述薄膜过滤管的一个实施例并且与四个薄膜过滤子模块2相连。每个顶部元件26与滤出液管道28相连，以便在每个顶部元件26和滤出液管道28之间实现流体连通。在薄膜过滤管1用作顶部元件26时不再需要罩帽20。不需要罩帽20能允许在管1和滤出液管道28之间实现流体连通。In another embodiment of the present invention as shown in Figure 11, a membrane filtration device 25 comprises a top element 26 and a base element 27, wherein each filtration device is an embodiment of the membrane filtration tube described above and is associated with four Membrane filtration sub-module 2 is connected. Each top member 26 is connected to a filtrate conduit 28 for fluid communication between each top member 26 and the filtrate conduit 28 . The cover cap 20 is no longer required when the membrane filter tube 1 is used as the top element 26 . The absence of cap 20 allows fluid communication between tube 1 and filtrate conduit 28 .

另外，特别在图12a和12b中示出，每个基部元件27与一个清洗液管道11相连，以便在每个基部元件27和清洗液管道11之间实现流体连通。在薄膜过滤管1用作基部元件27时，罩帽20的螺纹轴22以螺纹方式与清洗液管道11上的一个相应孔相接合。同样，在最佳实施例中，也不再需要夹持装置7来将子模块2锁定在基部元件上。这是因为子模块2将或者通过重力或者利用固定在其顶部元件26内合适位置的子模块顶部和夹持装置7，而固定在基部元件27的相应轴环4内。Furthermore, as shown in particular in FIGS. 12 a and 12 b , each base element 27 is connected to a cleaning fluid conduit 11 in order to achieve fluid communication between each base element 27 and the cleaning fluid conduit 11 . When the membrane filter tube 1 is used as the base element 27 , the threaded shaft 22 of the cover cap 20 engages in a threaded manner with a corresponding hole in the cleaning liquid line 11 . Also, in the preferred embodiment, the clamping means 7 are no longer required to lock the submodule 2 on the base element.

过滤装置排29另外还适于相对容易地从薄膜过滤装置阵列上拆下。当拆卸时，过滤装置排可以通过垂直地从该阵列上提升该装置排而从阵列上卸下。相似地，装置排也可以通过垂直地将装置排放进预定位置上而逐个地放置进阵列中。这样就使阵列的装卸变得更容易并且能更方便地接触到放置在阵列中心或靠近中心的子模块。Filter row 29 is additionally adapted to be relatively easily removed from the membrane filter array. When disassembled, the filter device row can be removed from the array by vertically lifting the device row from the array. Similarly, rows of devices can also be placed one by one into the array by vertically arranging the devices into predetermined positions. This allows for easier handling of the array and better access to submodules placed at or near the center of the array.

根据本发明的另一方面，提供了一个薄膜过滤装置阵列队，如图15所示包括若干图14所示的薄膜过滤装置阵列，其中滤出液管道阵列32通过管道阵列队33而连接，这样滤出液管道阵列32与管道阵列队33实现流体连接。According to another aspect of the present invention, a membrane filtration device array team is provided, as shown in Figure 15, comprises several membrane filtration device arrays shown in Figure 14, wherein filtrate pipeline array 32 is connected by pipeline array team 33, like this The filtrate pipeline array 32 is in fluid connection with the pipeline array team 33.

在过滤过程中，箱体31基本上连续地被填满物料，该物料依次将过滤子模块2的阵列浸没住。泵34通过从过滤子模块2抽取物料而生成滤出液。泵34所抽取出的负压下的滤出液，穿过管1，通过滤出液管道28、滤出液管道阵列32以及滤出液管道阵列队33并到达泵。滤出液随后离开泵，同时也通过一滤出液出口管道35而离开过滤系统。During the filtration process, the tank 31 is substantially continuously filled with material which in turn submerges the array of filter submodules 2 . The pump 34 generates a filtrate by drawing material from the filtration submodule 2 . The filtrate under negative pressure extracted by the pump 34 passes through the pipe 1, passes through the filtrate pipeline 28, the filtrate pipeline array 32 and the filtrate pipeline array 33 and reaches the pump. The filtrate then exits the pump and also exits the filtration system through a filtrate outlet conduit 35 .

尽管已经通过特定实例以及使用在对大气开放的过滤系统中的过滤管对本发明进行了描述，但是本领域技术人员能理解到本发明可以实现，以许多其它形式，包括使用在与大气相密闭的过滤系统中的过滤管。Although the invention has been described in terms of specific examples and use of a filter tube in a filter system open to the atmosphere, those skilled in the art will appreciate that the invention can be practiced in many other forms, including use in a filter tube closed to the atmosphere Filter tubes in the filter system.
